These poles make it so easy to hand your backdrops without the creases of when you use just clamps, I have set up all my backdrops with these and they rise and lower so easy thanks
If you buy the aluminum core pieces to hold paper - be aware that they are ten feet in width. The extra foot changed my initial room plan. The unit is easy to move. I bought adhesive levels and stuck them on the sides to help with straightness.
Tried first mounting my stands on PVC pipe from rona which was over $20 per roll. The pipe sagged really bad with the weight of the green screen but this was perfect. Highly recommend!
